Page 10: General Information
PART II General information Introduction This section gives you all the necessary informations to maintaine the DC power sup- ply module. It also specify how to modify the printer to operate on DC supply instead of AC supply. Principle of operation The power supply module is constructed to operate from a battery voltage of 10.5V DC to 32V DC to deliver the necessary voltages for the printer. -
Page 11: Maintenance/Modification
PART II Maintenance/modification This section is intended for use when modifying the printer to operate from DC supply instead of 220V AC supply. Disassembling to remove the mains transformer Remove the access cover by lifting up rear edge. Pull out the platen knob. Remove the two screws. -
Page 12: Disassembling And Mounting Of The On-Off Switch
PART II Disassembling and mounting of the ON-OFF switch It is necessary to remove the ON-OFF switch from the transformer assembly to use it again on the DC power supply module. Remove the filter and switch board from the transformer by pulling it off. Unsolder the ON-OFF Switch. Solder the switch to the two loose wires on the DC power supply module. Then twist the wires to the switch to suppress noise. -

PART II Run the printer selftest programme. Switch on the ON-OFF switch and simultaneously press down the “line feed” button. After a few seconds (at low input voltage) the printer starts the selftest printing routine, which means that the DC power supply is OK. Switch off the printer.

PART II Service Printer selftest To do a performance test of the DC power supply, a selftest programme in the printer can be used. Connect a DC power source of 10.5V to 32V to the DC input connector. Switch on the ON-OFF switch and simultaneously press down the “line feed” button. After a few seconds (at low input voltage) the printer starts the selftest a printing routine, which means that the power supply is OK. -

Page 18: Circuit Description
PART II Circuit description DC power supply To suppress noise on the supply wires a filter is build around the current compensated choke L1. Furthermore the RC snubbers across the transformer prevent unwanted oscil- lations during transition time. The diode D7 in conjunction with R16 and C19 clamps the transient voltage spikes across the switch transistor Q1. When the supply is switched on, the capacitor C6 is charged by means of R1 and when the voltage exceeds approx. - Page 19 PART II Component location DC power supply View from component side with upper side tracks.
